Electrical Engineers seldom show interest acquiring knowledge and experience on cable tray installations. Most of them think it's a concern of mechanical fabricators to be taken care of it. A proper and professional way of cable tray installation requires good involvement and coordination of people from both electrical and mechanical disciplines. If cable tray system has been installed appropriately in a project, following advantages can be counted:
Electrical engineering deals with practical applications involving current flow through conductors; focuses on the design, construction, and operation of electrical systems and equipment. It includes developing, producing and testing of electrical and electronic devices and equipment, such as, generators to produce and distribute electricity, electric motors and other electrical machinery, transmission line.
